pandas离散化cut

import pandas as pd
import numpy as np

df = pd.DataFrame([12,23,34,32,43,54,78,45,76], columns=["score"])
df

• 将连续值进行分区间

bins = [0,60,85,100]
pd.cut(df["score"], bins=bins)

• 设置文本标签

label = list("差中优")
pd.cut(df["score"], bins=bins, labels=label)

• 统计数量

d = pd.cut(df["score"], bins=bins, labels=label)
d.value_counts()
